Abstract

PURPOSE:To eliminate the limitation of the working frequency, by constituting a retriggerable multivibrator with two flip-flops. CONSTITUTION:The time constants C1R1 and C2R2 of the two integral networks 7 and 8 are selected as C1R1>>C2R2. When a pulse signal having the period T0 shorter enough than the time constant C1R1 is applied to the clock terminal of each flip- flop, the flip-flop 1 is not set with its Q output signal 4 kept at a low level. On the other hand, if the period T0 of the input signal is larger enough than the constant C1R1, the time working state decided by 0.7C1R1 is kept to give a restoration. When the input signal pulses are supplied consecutively, the working time is started at the time point when the final pulse of the input signals that continue in the time interval less than 0.7C1R1.
